The company has broken a run of sales decreases that stretches back six quarters thanks to promising early signs for the newly released iPhone 8, according to a new report from Canalys. The analyst firm recorded 40 percent annual growth for Apple in Q3 2017 with 11 million shipments during the three-month period. It noted also that the iPhone 8 accounted for a higher proportion of iPhone sales than the iPhone 7 did last year.

Apple's revenue from China is down by more than 50 percent from two years ago, according to its most recent Q2 earnings, so growth is much-needed. However, despite progress, the firm ranked only fifth in the Canalys report.

Huawei led the field with 22 million shipments, fractionally ahead of Oppo (21 million -- the only annual decline) and Vivo (20 million). Xiaomi, which is rejuvenated in 2017, came in fourth.

Beyond the raw data there are a few notable takeaways worth digging out.

Firstly to Apple, which Canalys believes is not out of trouble in China.

The impact of the iPhone X, the much-anticipated device that goes on sale November 1, isn't reflected in this report but already limited supply around the phone and its expensive price tag -- which starts at $1,000 for the most basic model -- may mean the phone doesn't deliver stellar growth that the U.S. firm saw in China when it released the iPhone 6, its first larger sized device.

"Apple is unlikely to sustain this growth in Q4," Canalys' Mo Jia said in a statement.

"While the iPhone X launches this week, its pricing structure and supply are inhibiting. The iPhone X will enjoy a healthy grey market status, but its popularity is unlikely to help Apple in the short term," Jia predicted.

The top five sellers in Q3 2017, according to Canalys' numbers, accounted for a massive 75 percent of all devices shipped in China. The analyst firm is predicting that Xiaomi may break into the top three thanks to its usually impressive performance on China's major online shopping day -- 11/11 -- and offline retail, but, that side, it is hard to see any others making headway on the top players at this point.

That's particularly important because data suggests that growth in the Chinese smartphone market is topped out.
